[3] Following clashes with the Israeli Defense Forces, another jihadist organization in the Gaza Strip, Jaysh al-Ummah (also known as the Army of the Ummah), began fighting Masada al-Mujahideen due to disapproval of their activities.

[6] The group then moved its operations to Facebook,[7] where it created eulogies for Osama bin Laden,[8] Attiya Allah,[9] and Abu Yahya al-Libi.

[18] In 2012, they claimed responsibility for an arson attack in Be'er Ya'akov[19] and set a military base in Ashkelon, owned by the Israel Defense Forces, on fire.
